Physiology in relation to energy metabolism.

Extracts from this document...

Introduction

Energy Forms Chemical The energy released when substances combine or break down and form new substances http://www.nmoga.org/glossary-of-terms An example of chemical energy is when a log is burnt Heat Heat energy is a form of energy which transfers among particles in a substance by means of kinetic energy of those particles. http://physics.about.com/od/glossary/g/heat.htm Heat energy can be formed by rubbing two hands together quickly due to friction. Electrical Electrical energy is the presence and flow of an electric charge. http://www.wisegeek.com/what-is-electrical-energy.htm An example of electrical energy is receiving a static shock. Light Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400-700 nm), or perhaps 380-750 nm. ...read more.

Middle

An example of this is a pendulum as long as no external factors, such as friction or wind resistance, were to implicate the movement the pendulum would swing forever at the same speed and height. Energy transformation The law of Energy transformation explains that energy is never lost but is converted into a different form of energy. An example of this is when wood is burned to produce heat, light and sound energy. Cardiovascular System Anabolism The cardiovascular system provides the body's cells with the oxygen, obtained through the respiratory system, and nutrients, that are provided by the digestive system, they need to generate energy and with the building blocks they need to make larger molecules. ...read more.

Conclusion

Catabolism The Respiratory System also provides a platform for excreting carbon dioxide one of the waste products of cellular metabolism. This is also completed through the use of gaseous exchange. The removal of this waste product ensures that there is space for the oxygen to be collected to meet cellular demand. Digestive System Catabolism The digestive system breaks down food so Catabolic enzymes can harness the nutrients from food and transmit them to the cardiovascular system so the nutrients can be circulated around the body for cellular metabolism. Anabolism The digestive system uses nutrients and oxygen from the cardiovascular system so the tissues of the system can be maintained and enzymes can be produced. ?? ?? ?? ?? 5.4 P1: Physiology in relation to energy metabolism.

    Cell respiration is the process by which food is broken down by the body's cells to produce energy. Anaerobic cellular respiration occurs in the cytoplasm when no oxygen is present for the cell to continue respiration after glycolysis. This stage does not need oxygen and occurs in the cell cytoplasm.

    The movement of the particles is due to kinetic energy. The boiling of water results in a transition from a liquid to a gas. You are able to get water at 100�c and also steam at 100�c. However, steam has more kinetic energy than water so will therefore burn more than water at 100�c.

    Electricity is the name given to electrical charges that move through a conductor. Electrical energy is easily transformed into other forms of energy, it changes in order to meet particular needs. An electrical current is what transports electrical energy in areas of the body where it is needed and transforms it into other forms of energy.

    into a network of smaller arteries that provide oxygen and nourishment to the muscles of the heart. Unlike the aorta, the body's other main artery, the pulmonary artery, carries oxygen-poor blood. From the right ventricle, the pulmonary artery divides into right and left branches, on the way to the lungs where blood picks up oxygen.

    Energy metabolism is the energy that is used by the body to maintain all the internal function working constantly. The role of energy in the body is linked to two body systems; the Digestive system and the cardiovascular system. These two body systems are involved in the role of supplying energy in the body.
